I had a dental implant put in about 7 years ago to replace an adult tooth that was never there. I later had a second implant to replace the neighboring tooth that was damaged due to earlier advice (that I wish I'd never taken) to use a crown with an attached fake tooth to solve the problem of the original missing tooth. That neighboring, originally healthy tooth ended up requiring a root canal, and it eventually broke. Does all of that make sense?
I am very happy with the first implant. However, when the crown was put on for the second implant, I didn't realize that it was too high until I bit down on something hard. This caused the implant to loosen in the bone. I had the crown fixed and we waited to see if the implant would firm up again. During the following 18 months, it seemed like it was tightening, then it would loosen again. It never really completely firmed up and eventually it became infected and had to come out. I am having that implant replaced in a few weeks.
I still have zero problems with the first implant and am happy I went with that option. As to the second implant, it is very important to make sure the bite is correct when the crown goes on, but my experience is not preventing me from replacing the implant - I'll just be super careful to make sure the crown fits well this time.
After having previously experienced the "fake tooth attached to the crowned neighboring tooth" solution, I find the daily care of the implants to be much easier than trying to floss under that fake tooth. It's like the implant is a regular tooth. I brush well, floss around the implants, and have my teeth cleaned by the dentist and periodontist every three months, alternating between them. The actual recommendation was to have a cleaning every four months, but the three-month schedule works for me.
The cost of the implants hurts, and even more so since I'm paying for the second implant twice, but I have no regrets, other than not having noticed that the crown was too high. Going with implants is also an option to fill an empty space that does not require changes to the neighboring teeth.
Best of luck to your daughter.
